Integration of primary care and behavioral health care is essential for improving health and lowering costs. Provisions in the Affordable Care Act are adding momentum to integration initiatives that have been implemented in recent years. However, the term “integration” is used inconsistently and applied to a wide variety of care models. Without an agreed-upon framework to classify integrated care settings more precisely, meaningful discussion and informed comparisons cannot move forward. The Center for Integrated Health Solutions (CIHS) has recently proposed a standard framework for classifying care settings according to their level of integration.
